Everyday Calculators
Percentage Calculator — Percent Of, Percent Change & More
Three percentage jobs in one tool: work out a percent of a number, find what percent one number is of another, and calculate percentage increase or decrease.
Open toolAI Food Calories Calculator
Calorie tables fail on real meals — nobody's lunch is '100 g of generic chicken'. This calculator takes the meal as you would describe it to a friend ('a plate of chicken biryani, a bowl of raita, a glass of sweet lassi') and estimates each item's portion, calories, protein, carbs and fat from standard published nutrition values, then totals the meal. Portions are the biggest source of error, so include rough amounts when you know them ('two cups', 'a large slice'). Every figure is an honest estimate — useful for awareness and tracking, not a lab measurement.
This tool is powered by AI running on a free service tier, so a generation can occasionally take a little longer or ask you to retry at busy times. Your input is sent only to produce your result — it is not stored.
How to use this tool
- Describe the meal, with rough amounts where you can — “a plate of chicken biryani and a glass of lassi”.
- Click Estimate calories.
- Read the per-item table and the meal total.
- Remember these are estimates from standard values — packaging and recipes vary.
Worked example
Describing “two scrambled eggs on buttered toast with a cup of black coffee” returns an item-by-item table — eggs, toast with butter, coffee — with calories, protein, carbs and fat for each, and a summed total for the meal.
Frequently asked questions
How accurate are the estimates?
Within the range honest estimation allows — typically ±15–25% on home and restaurant meals, mostly because portions and oil are unknowable from a description. Weighing ingredients is the only way to do better; this tool trades a little precision for a lot of speed.
How do I get a better estimate?
Add amounts and cooking details: 'fried in butter' versus 'grilled', 'large' versus 'small', brand names for packaged food. Every concrete detail you add removes a guess the AI would otherwise have to make.
Does it handle mixed dishes like curries and biryani?
Yes — mixed dishes are estimated as whole items using standard recipes for that dish, which is why naming the dish precisely ('Hyderabadi chicken biryani') beats listing vague ingredients.
Can I use this for medical or diet planning?
For general awareness, yes; for medical nutrition — diabetes, kidney conditions, eating-disorder recovery — no estimate tool is a substitute for a dietitian who knows your case. Track trends with it, not treatments.
Why did the same meal give slightly different numbers twice?
Portion estimation involves judgment, and two runs can land on slightly different reasonable portions. The totals stay in the same band; if you need consistency, state exact weights in your description.
